History Of Bioethanol Presentation

The History And Development Of Bioethanol As An Alternative Fuel Christopher McAtominey

Overview • What is bioethanol? • Why bioethanol as an alternative fuel? • The future of bioethanol

Ethanol • Produced by hydrating ethylene or by fermenting sugars CH3CH2OH + 3O2 2CO2 + 3H2O • First ever engine ran on ethanol • Used as a rocket fuel in WW2

Bioethanol • Produced by fermenting sugars • Sugars are from natural sources (biomass) eg sugarcane, maize • Burnt as fuel • Widely used in Brazil

Alternative Fuels • Climate change • Depletion of crude oil • Legislation

Alternative Fuels • Carbon neutral • Independence • Efficiency

Alternative Fuels Alternative Fuels

Future of Bioethanol • Currently only processed from sugars • Aim is to convert all biomass to ethanol • Engineering microorganisms

GM • Alcohol resistant yeast • 1.5 x 10 tonnes of biomass is cellulose 12 • Cellulases convert cellulose into sugars

Problems • Currently not carbon neutral • Cellulases do not work well in vitro • Predicted that hydrogen will be major fuel of future
